Adiponectin receptor 1

Adiponectin receptor 1 (AdipoR1) is a protein which in humans is encoded by the ADIPOR1 gene. It is a member of the progestin and adipoQ receptor (PAQR) family, and is also known as PAQR1.

Structure
Similar to G protein-coupled receptors (GPCRs), AdipoR1 also possesses 7 transmembrane domains. However, AdipoR1 is orientated oppositely to GPCRs in the membrane (i.e., cytoplasmic N-terminus, extracellular C-terminus) and does not associate with G proteins.

Function
The adiponectin receptors, AdipoR1 and AdipoR2, serve as receptors for globular and full-length adiponectin and mediate increased AMPK and PPAR-α ligand activities, as well as fatty acid oxidation and glucose uptake by adiponectin. In 2016, the University of Tokyo announced that it would launch an investigation into claims of fabrication of AdipoR1 and AdipoR2 identification data, as accused by an anonymous person/group called Ordinary_researchers.
